the big speech of the night is first lady michelle obama. she will be talking about her husband's policies and how he can relate to the struggles of the middle class. we also have senate majority leader harry reid speaking tonight, he is supposed to talk about something he has been discussing for a while, mitt romney tax record. we will have a video appearance by former president carter. >> will the democrats do anything to counter attack the gop version of clint eastwood? >> there has been some talk that betty white might make an appearance here. there was really no talk of her talking to an empty chair or anything but we understand she had some scheduling conflicts so we do not know about any other mystery guests. >> to democrats are expected to approve their platform today, does it include anything new or something we haven't heard before? >> it is all very familiar, the polar opposite of the republican platform. it does include support for abortion rights. same-sex marriage. it follows president obama's why he needs another four years. >
